Radio Shack Cat. No. 22-306 Frequency Counter with field antenna.

Selling as-is. This is a recent find from an estate sale. Please refer to the pics. This digital frequency counter ranges from 0-10Mhz, 1Mhz to 50 and 50Mhz to 1.3Ghz. 50ohm and HiZ impedance switch for the input. The counter runs on four (4) AA style batteries, alkaline or Ni-Cad, or a DC 9Volt power plug. An antenna is included, no adapter or rechargeable batteries are included. Standard AA cells are not included. The outside of the device is painted metal with plastic or vinyl accent grips and bottom feet. The case has some wear, see the pics. The battery compartment is clean! The backlight works. All buttons and switches appear functional. I was able to detect channel 40 Citizens Band radio when transmitting from a handi-talkie. Banana for scale :) Thank you for looking...
